Comparison of scanning depth in widened root canals: An analysis of three intraoral scanners and two scanning techniques.

Statement Of Problem: Although intraoral scanners have been increasingly utilized as alternatives to conventional impression techniques, their precision in capturing the complex anatomy of prepared widened root canals, essential for post placement after endodontic treatment, remains underexplored.

Purpose: The purpose of this in vitro study was to assess the efficacy of different intraoral scanners in scanning widened root canals. The study analyzed the depth (mm) and surface area scanned (mm) and compared 2 scanning techniques.

Cardiopulmonary Imaging Utilization and Findings among Hospitalized COVID-19 Patients in Latin America: (From "RIMAC: Registry IMAging Cardiopulmonary among Hospitalized COVID-19 Patients in LATAM").

Objectives: Describe the use and findings of cardiopulmonary imaging-chest X-ray (cX-ray), echocardiography (cEcho), chest CT (cCT), lung ultrasound (LUS), and/or cardiac magnetic resonance imaging (cMRI)-in COVID-19 hospitalizations in Latin America (LATAM).

Background: There is a lack of information on the images used and their findings during the SARS-CoV-2 pandemic in LATAM.

Methods: Multicenter, prospective, observational study of COVID-19 inpatients, conducted from March to December 2020, from 12 high-complexity centers, in nine LATAM countries.

Overexpression of a putative nitrate transporter (StNPF1.11) increases plant height, leaf chlorophyll content and tuber protein content of young potato plants.

Nitrate (NO3-) fertilisers are commonly used to improve the yield and quality of most non-legume crops such as potato (Solanum tuberosum L.). Root cells absorb nitrate from the soil using plasma membrane-bound transporters.

Trends and the Economic Effect of Asbestos Bans and Decline in Asbestos Consumption and Production Worldwide.

Although some countries have reduced asbestos consumption and instituted bans, other countries continue to produce and consume asbestos even as asbestos-related deaths mount and the associated societal costs are high. Asbestos production and consumption has declined globally; the number of bans has increased; and the speed at which countries have tapered off consumption has increased. Using country-level data, we study the economic impact of historical changes in the production and use of asbestos.

[Optimization of registry of deaths from chronic kidney disease in agricultural communities in Central America].

Several Central American countries are seeing continued growth in the number of deaths from chronic kidney disease of nontraditional causes (CKDnT) among farm workers and there is underreporting. This report presents the results of a consensus process coordinated by the Pan American Health Organization/World Health Organization (PAHO/WHO), the United States Centers for Disease Control and Prevention (CDC), and the Latin American Society of Nephrology and Hypertension (SLANH). This consensus seeks to increase the probability of detecting and recording deaths from these causes.
